What is emitted mainly during a nuclear detonation?

Shockwaves and thermal radiation are mainly emiited in a nuclear detonation. When the nuclear blasts hits the ground, kinetic energy from the impact will be released, similar to an earthquake, causing shockwaves. Thermal radiation, or electromagnetic radiation, a result of energy released from the nuclear reaction of two nitrogen atoms forming a carbon and an oxygen atom, causes fires, thermal burns and blindness.
